I don't have a picture of the plant right now, but I can get one tomorrow. We are growing in an aerogarden indoors. The watering schedule is automated, so I'm not sure what that is. Our growing medium is rockwool and I think we are close to the flowering stage. We noticed today that maybe 1/4" to 1/2" from the bottom of the stem, the stem is skinnier. It's thick below the thinner part and thick above the thinner part. We moved them earlier and one completely fell over! 
We went ahead and splinted that one, along with all of the other ones. Any ideas why this would happen? It looks almost like whatever was wrong with them, isn't wrong anymore since below the thin part it is thick again.
